Previous posting had OP thinking he was going to catch a boat loada fish on snorkel (ok ok, I'm embellishing). My only point was its not as easy to catch fish on the open reef, even on scuba with the proper nets and guidance. IF you're just goofing off in the tide pools...thats a different story. I would suggest you get some 'reefing' shoes....same as scuba type neoprene boots with hard rubber soles. you'll get cut up if you are bare footed. This is more in lne with toodeling around, not true fish collecting. if you're going for some snails, crabs, starfish.....have fun. There is a bit of allure and draw to going out and messing around at low tide....i track the tides religously, and will even take a day off work if its low enough.
